A much cleaner "install" of SDWebImage would be as follow:
SDWebImage 的更干净的“安装”如下：
- Drag SDWebImage folder from Finder into your Xcode's project
On any .m file where you wish to use it add:
#import "UIImageView+WebCache.h"(and any other SD component needed)
instead of what you probably did:
#import <SDWebImage/UIImageView+WebCache.h>
- 将 SDWebImage 文件夹从 Finder 拖到您的 Xcode 项目中
在您希望使用它的任何 .m 文件中添加：
#import "UIImageView+WebCache.h"（以及任何其他需要的 SD 组件）
而不是你可能做的：
#import <SDWebImage/UIImageView+WebCache.h>
this does not require any project header manipulation and will work as is.
这不需要任何项目标题操作，并且将按原样工作。

It may happen that:
可能会发生以下情况：
Unzipping this framework, the directory name may be the following: "SDWebImage-3.3.framework"
解压这个框架，目录名可能如下：“SDWebImage-3.3.framework”
If you import the project this way, causes the error "framework SDWebImage not found" when compiling.
如果以这种方式导入项目，会导致编译时报错“framework SDWebImage not found”。
You need renaming, deleting "-3.3". Would be: "SDWebImage.framework"
您需要重命名，删除“-3.3”。将是：“SDWebImage.framework”
Forcing the renamed from Xcode, causes a bug that close unexpectedly the IDE. Renames from Finder and add framework again.
强制从 Xcode 重命名，会导致 IDE 意外关闭的错误。从 Finder 重命名并再次添加框架。

I would not wish my worst enemy the frustration I had to go through to fix this problem because none of these solutions helped in my particular case. If your project compiled earlier, you came back to it and this error popped out of nowhere, chances are you've moved it to some new directory - so go to Build Settings > Search Paths > under Framework Search Paths delete the outdated path, create a new one and set it to "$(SRCROOT)" (without quotes) and change the default "non-recursive" to "recursive". I hope this spares someone the agony I endured.
我不希望我最大的敌人在解决这个问题时遇到挫折，因为这些解决方案在我的特殊情况下都没有帮助。如果您的项目较早编译，您又回到了它并且这个错误突然出现，很可能您已经将它移动到某个新目录 - 所以去构建设置>搜索路径>在框架搜索路径下删除过时的路径，创建一个新的并将其设置为“$(SRCROOT)”（不带引号）并将默认的“非递归”更改为“递归”。我希望这能让某人免于我忍受的痛苦。

Using #import <SDWebImage/UIImageView+WebCache.h>fixed the issue for me as I was using Cocoapods as frameworks (use_frameworks!).
使用#import <SDWebImage/UIImageView+WebCache.h>为我解决了这个问题，因为我使用 Cocoapods 作为框架（use_frameworks！）。

I had .xcodeproj and .xcworkspace files and launched the code using .xcodeproj and got this error, but with .xcworkspace it worked fine

The @Lizard answer saved my day!
@Lizard 的回答拯救了我的一天！
$(SRCROOT)/SDWebImage to Header Search Path
$(SRCROOT)/SDWebImage 到标题搜索路径
Just to be more specific, you have to add that configuration in your target and not in the project view.
更具体地说，您必须在目标中而不是在项目视图中添加该配置。

I got this error when I was removing some old unused Pods while keeping the XCode open. I have seen and read that you must keep XCode closed while doing any pod operation. Once pod operation is done, you should then reopen xcworkspace file and build.
当我在保持 XCode 打开的同时删除一些旧的未使用的 Pod 时，我遇到了这个错误。我已经看到并读到在执行任何 pod 操作时必须保持 XCode 关闭。pod 操作完成后，您应该重新打开 xcworkspace 文件并构建。
Did the same closed the XCode, but also I removed the contents of Derived data just to start from a fresh page. It worked !
同样关闭了 XCode，但我也删除了派生数据的内容只是为了从一个新页面开始。有效 ！
